NiMh 900 AAA Specification sheet

SUPREME POWER       Document Title: Product  specification of Ni-Mh 900 AAA
___________________________________________________________________

1.  SCOPE
         This specification governs the performance of the following Nickel Metal Hydride cylindrical cell and its stack-up battery.
          Model: AAA 900 mAh
          Cell size: AAA cusp ( 10.1-1X44.0/0.5mm)      
           AAA crew cut (10.0/0.1 x 43.5-0.5)mm

2.  DATA OF STACK UP BATTERIES
              All data involving voltage and weight of stack-up batteries are equal to the value of the unit cell multiplied by the number of unit cell which consisted in the                        stack-up batteries.
               Example: Stack-up batteries consisting 3 unit cells
                               Nominal voltage of unit cell=1.2 V
                               Nominal voltage of stack-up batteries=1.2 V x 3=3.6 V

5.  CONFIGURATION.  DIMENSIONS AND MARKINGS
            Please refer to the attached drawing

6.  EXTERNAL APPEARANCE
            The cell/battery shall be free from cracks, scars, breakage, rust, discoloration, leakage and defects

7.  WARRANTY
            One year limited warranty against workmanship and material defects.

8. CAUTION
             (1) Reverse charging is not acceptable
             (2) Charge before use. The cells/batteries are delivered in an uncharged state
             (3) Do not charge/discharge with more than our specified current
             (4) Do Not short circuit the cell/battery. Permanent damage to the cells/batteries may result
             (5) Do not incinerate or mutilate cells/batteries
             (6) Do not solder directly to the cells/batteries
             (7) The expected life may be reduced if cells.batteries are subjected to adverse conditions such as:
                   extreme temperature, deep cycling, excessive overcharge/ over discharge
             (8) Store cells/batteries in cool dry place. Always discharge batteries before packing
